 * Default order for post-processing effects. This can be used to sort effects by their rendering order when creating custom effects.
 * E.g. in your custom effect, you can set `order: PostProcessingEffectOrder.Bloom + 1;` to ensure it gets rendered after the bloom effect.
 * OR `order: PostProcessingEffectOrder.Bloom - 1;` to ensure it gets rendered before the bloom effect.
 * @example
 * ```typescript
 * import { PostProcessingEffectOrder } from "@needle-tools/engine"
 *
 * export class MyCustomEffect extends PostProcessingEffect {
 *    order: PostProcessingEffectPriority.Bloom + 1; // render after bloom
 *
 *    // ... your effect code
 * }
 * ```
